I didn't mention durability on vehicle applications as many panels used for camping spend limited time each year outdoors, there you might want watts per kg as much as anything. On houses reliability comes way up the top of your list.

Chase up the efforts of Origin Energy to build Sliver Cell technology panels, its a national disgrace that the factory to make them isn't being built in Australia. It's a wholly Australian invention!

I suggest that while longevity may not be a major consideration for vehicle applications, durability in the sense of standing up to being knocked about and handled is, much more so than watts per kg.

Nobody in their right mind would build a factory in Australia to make anything for worldwide sale - with a high Australian dollar guaranteed by long term high interest rate policies and high raw material exports, and regulations plus red tape guaranteeing high overhead costs, and often restrictive workplace practices added to high transport costs because we are remote from most major markets, almost anywhere else in the world makes more sense.

The fact are, monochrystalyn cells are most efficient at tempreatures below 20c. As a chrystaline substrate exposure to direct sunlight has a two fold negative, excessive heat absorbed by the structure, and a non alignment of the silicate to the azimuth of the rays. Got a theory, wvo too intercool the cells, given an ambient at marble bar 50+ off down the fish and chhippy to collect more reasearch.

maybe the method in the OP is just using the different refractive properties of different frequencies of EMR to split of the heating IR part of the spectrum and only feed the rest.
